CYLINDERS
Cylinders are planed and their cross-sections remain the same in all their length.
They are highly resistant to external conditions, and they are considered to be one of the strongest wood types because they consist of a full trunk and include the trunk heart in the middle.
Due to the fact that the trunk heart is in the middle, a crack is formed in the cylinder’s length. This is a completely natural wood reaction and does not affect its strength and durability.
